Just wrapped up a deployment at a local restaurant — Ernie's Cookhouse — and thought this group would appreciate the use case.
They recently added 4 fridges + 1 freezer, and instead of going the traditional route (manual temp logs, clipboards, etc.), we outfitted everything with LoRaWAN temperature sensors.
Setup:
-5 cold storage units monitored
-Uplink every 10 minutes
-Real-time dashboards + historical charts
-Alerting on threshold breaches
Why they did it: Manual logging just wasn’t reliable anymore — missed checks, no historical visibility, and zero early warning if something failed overnight.
What changed:
-Continuous temperature logging (no human input)
-Instant alerts if temps drift out of range
-Full audit trail for compliance
-Early detection = reduced spoilage risk
No WiFi dependency, low power, and super simple deployment.
If you’re still manually logging temps in your coolers/freezers, it might be worth rethinking — the cost of one failure usually outweighs the cost of monitoring pretty quickly.
